A child who weighs 40 kg receives a prescription for acetaminophen 15 mg/kg/dose PO every 4 to 6 hours PRN for fever. What is the maximum daily dose the nurse should administer? (Enter the numerical value only.)
Answer and Explanation

The Correct Answer is ["3600"]

Here's how to calculate the maximum daily dose of acetaminophen for the child:

Calculate the maximum dose per administration:

Maximum dose per kg per administration = 15 mg/kg (given)

Child's weight = 40 kg (given)

Since this is a PRN medication (given as needed), we will calculate the maximum dose per administration based on the prescribed dosage.

Maximum dose per administration = 15 mg/kg/dose * 40 kg

Maximum dose per administration = 600 mg (round to nearest whole number)

Calculate the number of administrations in a 24-hour period (maximum):

Frequency: Every 4 to 6 hours PRN (given)

Since this is a PRN medication, we will assume the maximum frequency (every 4 hours) for calculating the maximum daily dose.

Number of administrations (maximum) = 24 hours / Frequency (hours/administration)

Number of administrations (maximum) = 24 hours / 4 hours/administration

Number of administrations (maximum) = 6 administrations

Calculate the maximum daily dose:

Maximum daily dose = Maximum dose per administration x Number of administrations (maximum)

Maximum daily dose = 600 mg/administration * 6 administrations

Maximum daily dose = 3600 mg

Therefore, the maximum daily dose the nurse should administer is 3600 mg.

Correct Answer is ["60"]

Explanation

Here's how to calculate the gentamicin dosage per dose for the child:

Client weight conversion:

Client weight: 66 lbs

We need the weight in kilograms (kg) for the medication dosage.

Conversion factor: 1 kg = 2.205 lbs

Client weight (kg) = 66 lbs / 2.205 lbs/kg = 30 kg (round to nearest whole number)

Gentamicin dosage:

Prescribed dose: 2 mg/kg/dose (given)

Calculate the total gentamicin amount per dose:

Total dose (mg/dose) = Dose (mg/kg/dose) x Client weight (kg)

Total dose (mg/dose) = 2 mg/kg/dose * 30 kg

Total dose (mg/dose) = 60 mg (round to nearest whole number)

Therefore, the child should receive 60 mg of gentamicin sulfate per dose.

Correct Answer is ["22.9"]

Explanation

First, let’s convert the client’s weight from pounds to kilograms since the dosage is prescribed in mcg/kg/min. We know that 1 kg is approximately 2.2 lbs. So,

Weightinkg = 140lbs/2.2 ​≈ 63.64kg

The prescribed dose is 6 mcg/kg/min. Therefore, the total dose for this client per minute would be:

Doseperminute=6mcg/kg/min×63.64kg = 381.84mcg/min

We need to convert this to mcg/hr since we want the rate in mL/hr and our final concentration is in mcg/mL. There are 60 minutes in an hour, so:

Doseperhour = 381.84mcg/min×60 = 22910.4mcg/hr

The IV bag contains 250 mg of dobutamine in 250 mL of solution. This is equivalent to 250,000 mcg in 250 mL, or 1000 mcg/mL.

Finally, we can find the rate in mL/hr by dividing the dose per hour by the concentration:

RateinmL/hr = 22910.4mcg/hr / 1000mcg/mL ​ = 22.91mL/hr

If rounding is required to the nearest tenth, the nurse should program the infusion pump to deliver 22.9 mL/hr.
